Plyometrisen ja konsentrisen nopeusvoimaharjoittelun vaikutukset lihasjännekompleksin toimintaan ja rakenteeseen
2018
Voimaharjoittelulla on mahdollista saada muutoksia hermolihasjärjestelmän toimintaan ja rakenteeseen. Toistaiseksi on olemassa vähän tutkittua tietoa plyometrisen nopeusvoimaharjoittelun vaikutuksista lihasjännekompleksin toimintaan ja rakenteeseen. Tutkimuksen tarkoituksena oli määrittää plyometrisen ja konsentrisen nopeusvoimaharjoittelun vaikutuksia lihasjännekompleksin toimintaan ja rakenteeseen 12 viikon harjoittelun aikana. Tutkimukseen osallistui 12 20-30 –vuotiasta tervettä miestä, jotka jaettiin kahteen ryhmään (konsentrinen; CON ja plyometrinen; SSC). CON ryhmä suoritti harjoittelun paineilmalaitteilla ja SSC ryhmä hyppyharjoitteluna kelkkaergometrissä. Molemmat ryhmät harjoitteli…
Spatial localization of hotspots in Fano-resonant plasmonic oligomers for surface-enhanced coherent anti-Stokes Raman scattering
2020
AbstractRealization of Fano resonance in plasmonic oligomers is often exploited to design efficient plasmonic substrates for surface-enhanced coherent anti-Stokes Raman scattering. Disk-type Fano-resonant plasmonic oligomers are widely used to enhance the Raman signal of the probe material. Generally, hot spots are generated in those oligomers at different spatial locations at different wavelengths and only a few spatially overlapping hot spots at multiple wavelengths can be achieved with oblique incidence of excitation light. In this work, we proposed hexagonal gold nanoparticle based Fano-resonant plasmonic oligomers that can yield higher number of spatially overlapped hot spots compared …
Fabrication-friendly polarization-sensitive plasmonic grating for optimal surface-enhanced Raman spectroscopy
2020
Plasmonic nanostructures are widely utilized in surface-enhanced Raman spectroscopy (SERS) from ultraviolet to near-infrared applications. Periodic nanoplasmonic systems such as plasmonic gratings are of great interest as SERS-active substrates due to their strong polarization dependence and ease of fabrication. In this work, we modelled a silver grating that manifests a subradiant plasmonic resonance as a dip in its reflectivity with significant near-field enhancement only for transverse-magnetic (TM) polarization of light. We investigated the role of its fill factor, commonly defined as a ratio between the width of the grating groove and the grating period, on the SERS enhancement. We des…
Elucidating the ligand shell structure and dynamics of Au683MBA32 gold nanocluster using molecular dynamics simulations
2017
Synthesising novel gold nanoparticles and -clusters can be often easier than characterising them, and after experimental analysis many options for the possible molecular formula of the cluster may remain as equally valid options. These options may be investigated by quantum computational means, such as density functional theory, but since DFT includes the electronic interactions, this might take time and excessive effort if the amount of options is large. In this thesis a new way of easing the computational task is introduced by a novel method, that combines a guessing algorithm and molecular dynamics simulations. The algorithm produces possible structures by utilising existing structures o…
Ulomman reisilihaksen poikkipinta-alan kasvu 21 viikon voimaharjoittelujakson aikana harjoittelemattomilla 19-34 -vuotiailla miehillä : eri lihassolu…

Salmijärvi, Hanna 2008. Ulomman reisilihaksen poikkipinta-alan kasvu 21 viikon voimaharjoittelujakson aikana harjoittelemattomilla 19–34 vuotiailla miehillä; eri lihassolutyyppien vaikutus poikkipinta-alan kasvuun. Valmennus- ja testausopin kandidaatin tutkielma. Jyväskylän yliopisto. Liikuntabiologian laitos, 36s. Voimaharjoittelu harjoittelemattomilla saa ensin aikaan nopeaa voimatason nousua, mutta lihasten kasvua eli hypertrofiaa voidaan kuvantamismenetelmillä havaita vasta 16 harjoituksen jälkeen. Tyypin I lihassoluilla on kyky vastustaa väsymystä, mutta niiden voimantuotto on melko pientä. Tyypin IIa lihassolut ovat hyvin väsymystä vastustavia ja niiden voimantuotto on suurta. Tyypin …
A multiresidue analytical method for trace level determination of antibiotics and antiretroviral drugs in wastewater and surface water using SPE-LC-M…
2016
An analytical method for simultaneous determination of seven commonly used antibiotics and three antiretrovirals in surface water and urban wastewater at the ng L−1 level has been developed. The method involves concentration and clean-up by solid phase extraction (SPE) followed by identification and quantification by liquid chromatography tandem mass spectrometry (LC-ESI-MS/MS). The use of matrix-matched calibration curves constructed by spiking surface water was evaluated for quantification and compared with the internal standard method using isotopically labelled compounds. The method gave absolute recoveries of 41–116% with most of the compounds having recoveries >50%. The LOQs ranged fr…
Sunlit surface waters : exploring the photochemical reactivity of dissolved organic carbon
2017
In surface waters, solar radiation can photochemically mineralise the dissolved organic carbon (DOC, a measure of dissolved organic matter, DOM) to dissolved inorganic carbon (DIC). This DIC photoproduction constitutes an essential yet vague flux in the aquatic carbon cycling. The present thesis is based on the empirical assessment of the DOC photochemical reactivity, which was determined as the spectral apparent quantum yields (AQY) for DIC photoproduction. First, AQYs were determined in DOM solutions to quantify the impact of pH and DOM-associated iron. Then boreal lake waters were used for assessing the alteration of DOC photoreactivity due to water quality and catchment property. By sim…
